The number of people in workshop a is three-quarters of that in workshop B. if 60 people are transferred from workshop B to workshop a, then the number of people in workshop B is two-thirds of that in workshop a How many people are there in workshop a?
If there are x workers in workshop B, then there are 3-4x workers in workshop a
X-60 = 2|3 (3|4x + 60)
3x-180 = 2 (3|4x + 60), remove the brackets, get:
3x-180 = 3 | 2x + 120
3 | 2x = 300
x=200
Workshop a: 200 × 3 | 4 = 150 (people)
A: there were 150 people in workshop a
It should be like this, I hope my answer can bring you some help, I wish you progress in learning!
There are 210 people in the two teams. If we transfer 10% of the people from team B to team a, then the ratio of team a and team B is 4:3. How many people are there in team B?
B: now 210 (4 + 3) X3 = 90 people
B: 90 (1-10%) = 100
If you don't understand this question, you can ask,
How many minutes did they meet each other on the East and west of village a and village B, when they were 200 meters away from each other?
(10-250 minutes)
Distance between East and west villages: (250 + 200) X10 = 4500 (m)
Car a and car B start from two places 30 kilometers apart at the same time. Car a is behind car B. car a runs 58 kilometers per hour and car B runs 46 kilometers per hour. How long does it take car a to catch up with car B? If a car catches up with B car after X hours, the equation is___ .
Let car a catch up with car B in X hours. The answer is: 58x = 46x + 30
A and B start from a and B at the same time. When a goes to 27 away from B, B exceeds the midpoint of 30 kilometers. At this time, a travels 45 kilometers more than B. how many kilometers are there between a and B?
Let the whole distance be x km, from the meaning of the question: (1-27) x - (12x + 30) = 45 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 314
There are 210 people in workshop a and workshop B of cotton factory. If 110 people are transferred from workshop B to workshop a, then the ratio of the number of people in workshop a and workshop B is 4:3. How many people are there in workshop B?
210 × 34 + 3 △ (1-110), = 210 × 37 × 109, = 100 people; answer: there were 100 people in workshop B
Party A and Party B set out at the same time from two places with a distance of 6000 meters, and they met on the way 20 minutes later?
Let B run x meters per minute, then a's speed is (x + 60) meters
The carbon content of bituminous coal is 58.52%. How much flue gas can be produced by burning 1 ton of such coal?
It is urgent to solve the problem in time. It is added that the ash content of bituminous coal is 5.6%, the volatile matter is 35.88%, and the heat is 7848ka / kg. If calculated by 0.6 tons per hour, what is the combustion temperature?
The furnace for melting lead, the temperature of liquid lead is 500 ℃, and the fan model is 4-72-5a
What kind of furnace are you? How many degrees of combustion do you know? The amount of flue gas is generally determined by the air volume of induced draft fan
A and B start from ab at the same time and travel in opposite directions. When a goes to two seventh of the distance from B, B exceeds the midpoint by 30 meters. This is the fact that a travels 45 kilometers more than B, and how many kilometers is the distance between AB and B?
7 * 2 / 1 = 3.5 3.5 + 2 = 5.5 7-5.5 = 1.5 30 + 45 = 75 75 / 1.5 = 50 50 km is one seventh of 50 * 7 = 350 km. What else do you need
Do you need process or answer directly???? Hope to adopt it in time, thank you for asking: process
Two thirds of the number a is equal to six fifths of the number B. the sum of the numbers a and B is 162. What are the numbers a and B?
In ten minutes,
Let a be x, then B be 162-x
2/3*X=6/5*（162-X）
The solution is x = 729 / 7
A is 729 / 7, B is 405 / 7
